図1は、実施の形態1における映像表示装置の構成および観察者との位置関係を示す概略図である。図1に示すように、映像表示装置は、映像表示手段21および映像分離手段22を備える。 (Embodiment 1)
FIG. 1 is a schematic diagram showing the configuration of the video display device and the positional relationship with the observer in the first embodiment. As shown in FIG. 1, the video display device includes a video display means 21 and a video separation means 22.
<変形例>
図2に示した第1映像および第2映像の表示パターンにすると、第1映像を表示する列および第2映像を表示する列は、4列に1列しか存在しないため、立体映像の水平方向の解像度が垂直方向と比較して大きく劣化することになる。この問題に対して、実施の形態1の映像表示装置を図3~6に示すように変形することが可能である。 FIG. 2C is a diagram showing a state in which the video display means 21 is observed through the video separation means 22 from the
<Modification>
If the display pattern of the first video and the second video shown in FIG. 2 is used, there is only one column for displaying the first video and a column for displaying the second video, so that there is only one column in four columns. The resolution of the image quality is greatly deteriorated as compared with the vertical direction. To deal with this problem, the video display device of the first embodiment can be modified as shown in FIGS.
(実施の形態2)
実施の形態1の映像表示装置は、観察者の位置が変化すると、観察者の左眼に右眼用映像が、右眼に左眼用映像が観察される逆視の状態になる可能性がある。そこで、実施の形態2では、観察者の位置を検出し、観察者の位置に応じて表示を制御することで、観察者の位置が変化した場合においても、クロストークの発生や逆視の状態になることを抑制することが可能な映像表示装置について説明する。 Further, in the fourth modified example, as in the third modified example, since the bias in the arrangement of the first video (second video) in the horizontal direction and the vertical direction is reduced, the horizontal resolution is deteriorated with respect to the vertical resolution. Is reduced.
(Embodiment 2)
When the position of the observer changes, the video display device according to the first embodiment may be in a reverse viewing state where the right-eye video is observed in the left eye of the observer and the left-eye video is observed in the right eye. is there. Therefore, in the second embodiment, even when the position of the observer changes by detecting the position of the observer and controlling the display according to the position of the observer, the state of occurrence of crosstalk or reverse viewing A video display device capable of suppressing the occurrence of the problem will be described.
<補足>
以上、本発明に係る映像表示装置の実施の形態を説明したが、本発明の思想には、以下に示すものも含まれる。 With this configuration, it is possible to smoothly transition between the first state and the second state.
<Supplement>
The embodiments of the video display device according to the present invention have been described above, but the followings are also included in the idea of the present invention.
(9)上述の実施の形態では、映像を表示するサブピクセル列(第1映像列および第2映像列)および映像を表示しないサブピクセル列(第3映像列)が1列ずつ交互に並んでいるとして説明したが、映像を表示するサブピクセル列と映像を表示しないサブピクセル列の両方もしくは片方が複数列であってもよい。 (8) Instead of the light source control using the backlight and the light source used in the above embodiment, a method of controlling the light beam by arranging a fine light source such as a line light source or a step light source may be used. .
(9) In the above-described embodiment, the sub-pixel columns (first video column and second video column) that display video and the sub-pixel columns (third video column) that do not display video are alternately arranged one by one. However, both or one of the sub-pixel columns that display video and the sub-pixel columns that do not display video may be a plurality of columns.
(11)実施の形態2では、ある1つの開口部から観察される左眼視聴範囲81(右眼視聴範囲82)にある1つのサブピクセルが包含されるか否かを基準として、第1の状態と第2の状態を切り替える構成を説明した。別の実施例では、ある1つの開口部から観察される左眼視聴範囲81(右眼視聴範囲82)の水平方向の中心位置を基準位置として、当該基準位置が、あるサブピクセル群の中心位置と境界位置とのどちらに近いかによって、第1の状態と第2の状態を切り替える構成としてもよい。すなわち、当該基準位置が、当該サブピクセル群の境界位置よりも中心位置に近ければ、当該サブピクセル群に第2映像(第1映像)を表示する第1の状態とし、当該基準位置が、当該サブピクセル群の中心位置よりも境界位置に近ければ、当該サブピクセル群および当該境界方向に隣接するサブピクセル群の両方に第2映像(第1映像)を表示する第2の状態としてもよい。なお、第1映像、第2映像を表示する1つ以上のサブピクセル列をサブピクセル群とする。 (10) In the above-described second embodiment, the description has been made on the assumption that there is one observer, but there may be a plurality of observers. For example, when there are two observers (observer A and observer B), the video display means 21 has two display patterns corresponding to the observer A and two different display patterns corresponding to the observer B. The display pattern needs to be displayed. In this case, the video display means 21 alternately displays a display pattern corresponding to the observer A and a display pattern corresponding to the observer B in a time division manner. With this configuration, it is possible to suppress the occurrence of crosstalk and the reverse viewing state for both the viewer A and the viewer B, and to some extent have the effect of improving the image quality of the stereoscopic video. At that time, the position of the opening and the light shielding portion of the image separating means 22 may be changed, and the position of the opening and the light shielding portion of the image separating means 22 may be changed according to the display pattern.
(11) In the second embodiment, on the basis of whether or not one subpixel in the left eye viewing range 81 (right eye viewing range 82) observed from a certain opening is included, the first The configuration for switching between the state and the second state has been described. In another embodiment, the horizontal center position of the left-eye viewing range 81 (right-eye viewing range 82) observed from a certain opening is used as the reference position, and the reference position is the center position of a certain subpixel group. It is good also as a structure which switches a 1st state and a 2nd state depending on which is close to a boundary position. That is, if the reference position is closer to the center position than the boundary position of the sub-pixel group, the second image (first image) is displayed in the sub-pixel group, and the reference position is If it is closer to the boundary position than the center position of the sub-pixel group, a second state in which the second video (first video) is displayed on both the sub-pixel group and the sub-pixel group adjacent in the boundary direction may be set. One or more subpixel columns that display the first video and the second video are defined as a subpixel group.
